Abstract

Acute eosinophilic pneumonia is one of a recently described idiopathic eosinophilic lung disease, which differs from chronic eosinophilic pneumonia. Patients with acute eosinophilic pneumonia develop acute onset of dyspnea, hypoxemia, diffuse pulmonary infiltrates and pleural effusion on chest radiograph, and show an increase in number of eosinophils in bronchoalveolar lavage fluid or lung biopsy specimen. Prompt and complete response to corticosteroid therapy without any recurrence is characteristically seen in patient with this disease. Although the etiology of acute eosinophilic pneumonia is not known, it has been suggested to be related to a hypersensitivity phenomenon to an unidentified inhaled antigen. We report four cases of acute eosinophilic pneumonia presented with acute onset of dyspnea, diffuse pulmonary infiltrates on chest radiograph, and eosinophilia in bronchoalveolar lavage.'luid in previously healthy adults.
